To'all whom-.fit mag/romain: i l. 'Be it known A-that. I, CHARLES C. vARM- STRONG, a citizen of the' United States', resid*- .ingat llsa'rysville, Ohio, have invented ceri tain new Aandiuseful Improvements in Locks .or Fastening Devices for Hinged Box Memjbers, of which the following is a specification.

My 'present invention relates to locks or fastening devices `designed more especially niediate hinged ap,

to indicate corresponding parts. In the'drawlngs; Flgure 1 ls'a plan View of the tackle box in (fpened position. Fig. 2.

is a sectional view o the box in opened position. Flg. 3 is a sectional view-through I the lock mechanism lshowing this mechanism in position which willenable the lool; to beopened by pressure when the key is removed.- Fig. 4 illustrates therposition o the lock fp mechanism in locked position IFigr shows details of the lock mechanismiand, Fig. 6 is a sectional yview of the tackle'box in. closed position. Fig.' 7 shows details. i

In these-drawings i and 2 comprise the two main members of the box lwhich is shownv as represeilltative of my device to; rwhich my Improved lock or fastening Ina.'

be applied, each of which is shownvlnthe form of an elongated shallow tray, these two A members being hinged together at 3. The.

memberV 2 is provided with a. turned edge 4 and the member 1 is providedwith a fiared' Ledge 5 adapted to fit over the turned edge 4,

vwhen the member l is swung over upon the 'member 2 as shown in Fig. 6." A leaf ,onflap `.8. is provided hinged about the same axls as fthe-hinged members atI 3 and this hinge 'is preferably formed by projecting ears or porl 'l-; hinge rod andeach of the members l `and 2 'Y vrare likewise provided with hinged portions' ektending` around the saidrod. The flap or Sie adapted to cover either member 1,f 2

' applied to thebox atene 1n addition' to locking the bers together, will lock the position. by engaging the opening at 13 vformed vin said leaf. The wall of this opening at 13 is adapted to engage shoulder 14 in the catch 15 forming a part of the lock, this catch having an inclined i .65 to ride 'against and' spring the-leaf or Hap laterally 1n the dlrection of itsplane when..` I .1t 1s pressed down over the catch orthetcatchedge at lpfor the edge of the opening at 13 1s pressed into connection with the leaf.v A'

of the arrow in Fig. l'tospring` the leafv outof connection with'the shoulder 14 of the catch. There is suilicient play or spring of the partsto allow thisaction to be' performed.. The lock comprises the'catch l53y.hicheonsissofA catch also having an opening at 17 to'perinitf the insertion of a key.' The catch is lV held by its shoulders at @feudal engaging the wallsV of. a casing c andby a cover plate .f heldl to thevcasmg cyby proyections g on said easing passing through openings in the cover late' and bent over thereupon. .The catch Y has an opening'l adaptedto engage a proj jection 19 onv and` the catch the interior of the member 1 and'lower ends, the lower end of said 'spring Patented .rally 4., 1916. Application filed Hay 8, 1.915. Serial No. 26,841. I

the notch or eing necessary forhim however, t`o exert' slight pressure latcrallyor in the direction K is spring pressedby 'a leaf; sprmg engaglng vthe catclrat its upper point l2v and this, I .l two main mem iiap or leaf 8 in*` member bein burnedl back upon itself as if shown atQl. his spring member has a central i i openingthe upper and lower edges of which .at 22am bounded by flanges'extending up from the body of the plate.

This opening is of rectangular form and the iiange's or ribs ,22 are parallel with vveach other and afford surfaces against which -thebit2f3 of the key may worl. When the key is turned 'in the position shown in Fig. 3, the spring is moved' downwardly in said figure sothat the enlarged portion l21 of the spring member willl be lmoved down Voutside of thev lock casing and when the Akey is removed the lock can begmanipulated to openy the box by simplypressing with the finger inwardly upon the vkey ferrule24 because with the parts in th.

Iposition shown in Fig. 3 the spring will yielu vand"allow the catch 15 to bg moved inwardly or from the projection IQLLIfYQEl'ie, key ferrule 24C vis seated'in theca'singofthe loclif brits inner flange engaging a recess in the cover plate and this Jr'errule is Jfree to turn, it having a -slot Q5 adapted to receive the key. Non' when the key is turned to thc position shown in Fig. 4, Jfor setting the lock in retaining or locking position the spring member E20 vvill be moved`to the position shown in said figure with its enlarged end 21 lind ing a bearing against the inner side ot' the wall of the casing, as shown at y and with the parts in this position the spring at its enlarged end u'ill resist any bodily movement to the left on the part of the catch l5 in Fig. l and therefore pressure upon the key ferrule vvhich serves to unlock the parts or release the catch in Fig. 3 will not allect the leltward shifting or springing ot' the catch 15 in F ig. e and therefore the catch will maintain its engagement with the locking-lug or projection 1l) and the parts will be held together.

It will be seen from the above that in order to unlock the box it is necessary to manipulate the key and also to exert pressure of the finger upon the key ferrule axially thereof` when the key is removed.

The casing is provided with an openingr at to receive the shank or bearing 2G ot' the key. The spring plate is provided with shoulders to come against the inner side ot' the'casing and limit its throw, and to hold the. spring member against dropping out oi. said casing.

lt will be' noticed from the above construction that the device can be used as a lock with the key or as a latch without the key.

The box is made of metal throughout and is largely formedfot stampings both as to the box structurejtselt and also as to the lock and latch mechanism.

It will benoticed that the spring member Q0 has a-hump at 2U and this is borne upon by the turned end l5K of the atcb member 1li. The purpose of this hump is to restrain the spring member against accidental displacement or prevent it from being jarred out of the position in which it is set by the key. ln the position shown in Fig. il the end l5w of the catch will bear on the spring on the upper side of the hump and therefore this humpiwould have to pass by the end l5 in order to make it assume its other position but the spring resistance is such that the parts will be held in the relation shoivn` until the spring is positively operated by the key. In the position shown in Fig. la the hump is above the end of the catch and` therefore movement of the .catch downwardly except when operated positively by the key will be resisted.
